Yes you can do that like code below and link. http://developer.android.com/reference/android/os/AsyncTask.html

  private class DownloadFilesTask extends AsyncTask<URL, Integer, Long> {
         protected Long doInBackground(URL... urls) {
             int count = urls.length;
             long totalSize = 0;
             for (int i = 0; i < count; i++) {
                 totalSize += Downloader.downloadFile(urls[i]);
                 publishProgress((int) ((i / (float) count) * 100));
             }
             return totalSize;
         }

         protected void onProgressUpdate(Integer... progress) {
             setProgressPercent(progress[0]);
         }

         protected void onPostExecute(Long result) {
             showDialog("Downloaded " + result + " bytes");
